Hi!

If I can read this properly, you suggest to make the copy of the image to 
the second tape drive. But we need both tape drives for backup reasons. 
The image should only be dumped to a file. But I think, there would be the 
possibility to mount a image file as device and tell dd to copy the data 
to that one :-) Problem could be the variable size of this image device. 
But thnx a lot for your idea!

Bye,
Simon
